摘　　要：目的探讨小切口白内障手术两种切口术后视力及角膜散光的临床效果。方法选取本院2011年1月～2012年1月收治的白内障患者61例,共计76眼,均行白内障超声乳化吸除人工晶状体植入术,根据手术切口分为两组,38眼采用上方透明角膜隧道切口为对照组,38眼采用颞侧透明角膜隧道切口为观察组,比较两组患眼在术前、术后1周、术后1个月、术后3个月、术后6个月的裸眼视力和角膜散光情况。结果观察组在术后1周、术后1个月、术后3个月、术后6个月的裸眼视力均明显高于对照组,观察组在术后1周、术后1个月、术后3个月、术后6个月的角膜散光度均明显小于对照组,差异均有统计学意义(P<0.05)。结论白内障超声乳化吸除人工晶状体植入术中,颞侧透明角膜隧道切口的临床疗效优于上方透明角膜隧道切口,术后视力恢复更好且角膜散光更小。Objective To investigate the clinical effect of postoperative visual acuity and corneal astigmatism after two kinds of small incision cataract operation.Methods Sixty-one patients with cataract were selected in the hospital from January 2011 to August 2012 in our hospital.Total eyes were 76,which were treated with phacoemulsification and intraoc ular lens implantation.According to the operation incision,eyes were divided into two groups.38 eyes treated with upper part clear corneal tunnel incision as the control group.38 eyes treated with temporal side clear corneal tunnel incision as the observation group.Uncorrected visual acuity and corneal astigmatism were compared between two groups in the preop erative,postoperative 1 week,postoperative 1 month,postoperative 3 months,postoperative 6 months.Results Uncorrected visual acuity in the observation group were significantly higher than the control group after operation 1 week,1 month,3 months,6 months.Corneal astigmatism in the observation group were significantly smaller than the control group after op eration 1 week,1 month,3 months,6 months.The differences were statistically significant（P 〈0.05）.Conclusion In phacoemulsification and intraocular lens implantation,clinical effect of temporal side clear corneal tunnel incision is better than upper part clear corneal tunnel incision.Postoperative visual acuity is better,while corneal astigmatism is less.
